Perhaps most intriguingly, the presence of a ring could explain the onset of the Ordovician ice age. By partially blocking sunlight, especially at the equator, the ring may have triggered global cooling. As the ring dissipated over time and fewer impacts occurred, temperatures gradually recovered. ...
Many of them lack growth rings, suggesting a uniform climate. The presence of two large ice sheets at the southern pole was sucking up a huge amount of Earth's water, and because of this, the sea levels all over the world fluctuated. This led to another mass extinction, this time f...

For most of human history, the Sun appeared stable. It was a stoic stellar presence, going about its business fusing hydrogen into helium beyond our awareness and helping Earth remain habitable. But in our modern technological age, that facade fell away. We now know that the Sun is governed...
By examining Earth's geological history, scientists detected 21 impact craters within 30 degrees of the equator from the same time period. This pattern is highly unusual, considering most of Earth's landmasses lie outside this narrow equatorial band. The existence of a ring system di...
At the same time the atmosphere is almost opaque to the earth’s thermal radiation (owing to the presence of carbon dioxide and water vapors in the atmosphere—the greenhouse effect). If the earth did not have an atmosphere the average temperature of its surface would be -23°C, while in...

The earth’s surface and the hydrosphere, as well as the adjacent layers of the atmosphere and the earth’s crust, are jointly called the geographic, or landscape, shell. The geographic shell was the arena for the appearance of life, whose development was promoted by the presence on the ear...
The Elves are an eternal presence in the lands of Middle-earth. However, Rings of Power explains why the Elves will leave it behind in the Fourth Age.
